The conventional bobbin transfer device disclosed in JP-A No. 60-52475 has a U-shaped bobbin transfer device attached to a plurality of spinning machines. ), the full bobbin conveyor and the empty bobbin conveyor on the winder side are connected to a circulation conveyor which is the main conveyance path, and this circulation conveyor has a branch connected to the feeding section of the bobbin transfer device of each spinning machine. On the upstream side of the point, the outer periphery of the full bobbin that has been inserted into the header tray and transported comes into contact with a guide plate fixed on one side of the main transport path and moves straight along the path, and the header When the empty bobbin inserted in the tray is conveyed, the header tray is moved laterally to one side of the main conveyance path by another guide plate fixed on the other side of the main conveyance path, and the connected spinning machine A device for sorting full and empty bobbins which sequentially enters the feeding section side of the bobbin transfer device is provided together with a product sorting device.

In addition, on the upstream side of the branch point of the circulation conveyor that connects the feeding section of the conveyor for full bobbins on the winder side, the full bobbins and empty bobbins that have been inserted into the header tray and transported are sorted out, and only the full bobbins are left. Another full and empty bobbin sorting device is provided, which allows the bobbins to enter the feeding section of the full bobbin conveyor on the winder side.

Problems to be Solved by the Invention As mentioned above, the conventional bobbin conveying device separates and connects full bobbins and empty bobbins, which are mixedly conveyed along the main conveyance path, to the circulation conveyor, which is the main conveyance path. Only empty bobbins are sent to the bobbin transfer device of each spinning machine, and only full bobbins are sent to the full bobbin conveyor on the winder side.

In addition to the problems of requiring a sorting device for empty bobbins and complicating the bobbin conveying device, in the case of the conventional device mentioned above, in which all the conveying devices are installed on the floor, it is difficult for workers to pass through and for automatic transportation. It goes without saying that this will impede the movement of aircraft, etc., and that the floor surface cannot be used effectively.

Means for Solving the Problems In order to solve the above-mentioned problems, in the present invention, a main line for conveying a header tray that supports bobbins in an upright state is provided on one side of a plurality of spinning machines installed in parallel. Two @ring conveyors are installed underground, close to each other, perpendicular to the spinning machine table, and.

The circulating conveyor is connected to the winder and the header tray conveyance path of each spinning machine by a conveying means such as an inclined conveyor, thereby eliminating the drawbacks of the conventional apparatus.

Function: In the bobbin conveying device of the present application, a full bobbin doffed by a spinning machine is conveyed by a conveying means to a circulating conveyor that is a main line installed underground.

After being conveyed by the conveyor to a position corresponding to the winder, the conveyor is conveyed to the winder. Further, the empty bobbin rewound by the winder is transported by the transport means to the circulation conveyor, and after being transported by the conveyor to a position corresponding to each spinning machine, the transport means transports it to the peg tray transport path of the spinning machine. .
